deriveViewId

Derive a view id retrieved from calling calculateViewId(FacesContext), but
do not check if a resource with this name exists. This method is useful
to retrieve a VDL instance, but note there are some cases (TCK test) where
it is expected in Restore View algorithm a null or dummy viewId is passed.

Parameters:

context -

viewId -

Returns:

processComponentBinding

Processes the component tree. For each component (including the given one) in the tree determine if a value
expression for the attribute "binding" is defined. If the expression is not null set the component instance to
the value of this expression

Parameters:

facesContext -

component - the root component

isPostback

Determine if the current request is a post back by the following algorithm.

Find the render-kit-id for the current request by calling calculateRenderKitId() on the Application’s
ViewHandler. Get that RenderKit’s ResponseStateManager and call its isPostback() method, passing the given
FacesContext.
